Sheldon Cooper: Well, as a male, I have an evolutionary drive to perpetuate my DNA. Restricting myself to a single partner is against my nature.Amy Farrah Fowler: We sleep together once a year! You want other partners?Sheldon Cooper: Don’t blame me. Blame your pal, biology. He’s the pervert pulling the strings here.

Bernadette Rostenkowski-Wolowitz (to Howard): Can you please stop making money come out of me for two minutes?

Sheldon Cooper: I suppose I should apologize to you, as well.Penny Hofstadter: Okay.Sheldon Cooper: That must have hurt watching me look for other women without ever even considering you. Please understand that I think of you as more of a nanny.Penny Hofstadter: Just finish your ice cream so I can get you home to bed.
